7 Claims. (Cl. 285-443) The present invention relates to a wave guide and relates more .particularly to a wave guide device for detachably securing a removable section of the Wave guide in alignment with fixed sections thereof.

The present invention provides a wave guide of the type used in radar or other electronic applications where a section of the Wave guide may be removed and replaced without the use of tools. Such an arrangement permits the removable section to be changed or repairs to be made inthe shortest possible time as such equipment is often under conditions where it is of great importance that such changes or repairs be made with the utmost speed. The various objects and advantages of the invention will be apparent and best understood from the following description and the accompanying drawings in which:

Fig. 1 isa side view of a portion of a wave guide embodying the invention; Y

Fig. 2 is a plan view of the wave guide illustrated in Fig. l

Fig. 3 is an end view of the wave guide illustrated in Fig.' l;

Fig. 4 is a side View of a spring clip for holding a removable Section of the wave guide in place;

Fig. 5 is a rear View of the spring clip illustrated in Fig. 4;

Fig. 6 is a top view of the spring clip illustrated inFig. 4;

Fig. 7 is a side View of a latch for securing the removable section of the wave guide in place;

Fig. 8 is a rear view of the Support illustrated v in Fig. 7; and

Fig. 9 is a plan view of the support illustrated-in Fig. 7.

Referring now to the drawings in detail, there is a removable section lilr of a wave guide that is positioned between two fixed sections` H and I2 of the wave guide. The fixed sections Il and l2 vare provided with flanges f3 and I4 against which matching flanges i5 and the removable section l' abut. tions H' and i2 and the removable section i6 of the wave guide are hollow forming a rectangularly shaped passageway I1 through which ultra high frequency waves travel. When the removable section is appropriately positioned between the iixed sections il and I2, the sections are aligned with the passageways l1 of these sections forming a continuous and uninterrupted passageway through the wave guide.

Electronic devices such as vacuum tubes, as indicated at I8 may be incorporated in the removable section I of the wave guide. Such devices it on the ends of` The fixed sechave portions .thereof that are located. in the passageway Il where they will be Subject to the effects of the electrical impulses or Waves passing through the passageway il. Since the electronic devices i8 may require replacement ormay have to be changed for other reasons, it is desirable that such replacement or change be made .as easily and as quickly as .possible and the :present invention permits this to be done normally Without the use of tools or other instruments.'-r

' For this purpose, a pair .of spring clips. |9are secured to the flange .i3 ofthe fxedsection--I l of the wave guide. When the removablesection I0 is inserted between the .xedsections l! and l2.

the spring clips l@ resiliently engage with theback of the iiange l that is located at an end Aof the removable section i0 so as to hold theiacesjof the anges Il and l5 against each. other. .The

removable sections are aligned.

A resilient 'latch member 22 is also secured. to the flange i3 on the fixedsection il of. the Wave guide and engages with the bottom edgeofthe flange I5 on the removable section i 9 rofthe wave l guide and supports the flange i5 andthe-remov- ,i 4able sectionA lli vfvvhen the flange v|.51is inserted .be-

heath the spring .clips i9. 'Y The latch member 22,

as illustrated, consists of a pair of U-shaped spring lingers 23 with their ends located beneath the flange i5 of the removable section iil at the have been brought into engagement with the pro- -jeetions and 2l to align the sections 4of the wave guide properly, the spring fingers 23 are permitted to spring outwardly and serve as a support to hold the removable section Il) in place.

in the embodiment of the invention as illustrated and described herein without departing from the scope of the claims appended hereto.

We claim:

1. In a wave guide wherein a removable section of the wave guide is supported between fixed sections of the wave guide with passageways extending through said sections in alignment, the combination including a flange carried by one of the fixed sections of the wave guide, a second flange carried by the removable section of the Wave guide at one end thereof, the outer face of said second flange being in engagement with the outer face of the first-mentioned flange when the removable section of the wave guide is positioned between the fixed sections, aspring clip carried by one of said lianges to hold the faces of said flanges in engagement, and a resilient latch carried by one of said flanges and engaging with the other of said flanges when said flanges are held in engagement.

2. In a wave guide wherein a removable section of the wave guide is supported between fixed sections of the wave guide with passageways through said fixed and removable sections be ing in alignment, the combination including a `flange carried by one of the fixed sections of the wave guide at the end thereof, a second flange Vcarried by the removable section of the wave guide at the end thereof, the outer faces of said fianges being in abutting relation to each other when the removable section of the wave guide is positioned between the fixed sections, projections carried by one of said flanges, said projections positioning the removable section of the wave guide with av passageway through said removable section in alignment with passageways in said fixed sections, a spring clip carried by one of said flanges and engaging with the other of said flanges to hold the faces of said flanges in engagement, and a resilient latch carried by one of said flanges and engaging with the other of said liange when the faces of the flanges are held in engagement.

- 3; In a wave guide the combination as defined in claim 2 wherein the projections for positioning the flanges are integral with the spring clip.

4. In a wave guide wherein a removable section of the wave guide is supported between fixed sections of the waveguide with passageways extending through said sections being in alignment, the combination including interengaging members carried by said fixed and removable sections, said interengaging members positioning the removable section with a passageway extending through said section in alignment with passageways in said fixed sections, a spring clip carried by one of the fixed sections, said spring clip engaging with and holding the removable section in engagement with said fixed section, and a resilient latch carried by said fixed section and engaging with the removable section, said latch cooperating with the spring clip to hold the removable section in engagement with the fixed section.

5. In a device for detachably securing a section of the wave guide in place with a passageway in said section aligned with passageways in fixed sections of the wave guide, the combination including a spring clip, said spring clip having a spring finger associated therewith, laterally extending projections located at the top and one side of said spring finger, said projections being aligned'with and extending beyond a fixed section of the wave guide, and a resilient latch cooperating with said spring linger, said latch engaging with the detachable section of the WaveV guide.

6. In a device for detachably securing a Section of a wave guide in place with said detachable section connecting fixed sections of the waveguide, the combination including a pair of spring clips carried at the end of one of the sections of the wave guide, each cf said spring clips having 1ater ally extending projections located at the tops and sides thereof, said projections engaging with the adjacent end of an adjoining section of the wave guide, and aresilient latch carried at the end of one of the sections of the wave guide and engaging with the adjacent end of the adjoining section of the wave guide, said latch cooperating with the spring clips in maintaining the detachable section of the wave guide in position between the fixed sections.

7. In a device for detachably securing a section of a wave guide in place with said detachable section connecting fixed section of the wave guide, the combination as deiined in claim 6 wherein the resilient latch consists of a resilient U-shaped member, said U-shaped member being secured to one of the wave guide sections and having a free end engaging with the adjacent end of the adjoining wave guide section.
